Answer:
Balance with Fed on last day to be $ 800
Explanation:
Computation of balance on last day of maintenance period
Balance maintained $ 450 for 2 days $ 900
$ 700 for 3 days $ 2,100
$ 650 for 2 days $ 1,300
$ 450 for 3 days $ 1,350
$ 650 for 3 days $ 1.950
Average of balances maintained
13 days $ 7,600
Average balance maintenance required for 13 + last day)
$ 600 * (13 + 1) 14 days $ 8,400
so the balance with the Fed on the last day has to be
$ 8,400 - $ 7,600 $ 800
